Improvement in gas-carbureters



UNITED STATES PATENT QFFTGEQ CHARLES A. HOWARD, OF PONTIAC, MICHIGAN.

IMPROVEMENT IN GAS-CARBURETERS.

Specification forming part of Letters Patent'No. 222,822, dated December 23, 1879; application filed September 17, 1879. i

To all whom it may concern:

Be it known that I, CHARLES A. HOWARD, of Pontiac, county of Oakland, State of Michigan, have invented Improvements in Air or Gas Oarbureters; and I do hereby declare the following to be a full, clear, and exact description of the invention, which will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form a part of. this specification. I

My invention consists in a carbureting apparatus of the peculiar construction and combination of parts, as will hereinafter be described, and pointed out in the claims.

Leading from the smaller chamber is a secondary chamber perforated at its inner end I and stuffed full with Woolen fabrics, eXcelsior, shavings, charcoal, or other capillary substance which will present large surface to the air or gas passing through it. The air or gas to be carbureted enters the smaller chamber, passes through the secondary chamber, and is led off from its further extremity, while the float mechanism shuts off the supply of liquid before it can rise to the extent of filling the secondary chamber.

In the drawings, Figure 1 is a longitudinal central section of a device embodying my invention. Fig; 2 is a cross-section through the body of the tank. Fig. 3 is an end view, illus' trating the valve and float mechanism.

A is a tank or reservoir for containing a supply of gasoline or other liquid hydrocarbon. B is a chamber at its end, and connected therewith only by the valve 0 near the bottom, and the valve 0 near the top.

The valve-arms (l are connected at their 1 ends with the stem D of the float D.

E is a secondary chamber leading from the chamber B. Its inner end adjacent to the chamber is closed by a perforated partition, E. This chamber is stufl'ed full with pieces of cloth, wool, shavings, excelsior, charcoal, or any other cellular capillary substance which will present a large surface to the air or gas that is passed through it. From the farther end of the chamber E is an outlet-pipe, through which the carbureted air or gas is conveyed away to the place where it is to be burned or otherwise used. I

The operation of this apparatus is substantially as follows: When the float is at its lowest point the liquid hydrocarbon will flow through the valve 0 into the chambers B and E and lift the float. At the same time the upper valve, 0, is open, so as to establish an equi librium in the chambers A and B.

Whatever air or gas is fed into the chamber B through the inlet 1) must pass through the secondary chamber E, be there charged with.

the hydrocarbon, and escape from the orifice 0. It is therefore important that the flow of the liquid into the chamber B be checked beforeit rises to such a height as to close up the secondary chamber E. For this purpose the float D is provided, and when the liquid rises as high as may be desirable within the chambers B and E this float, being attached to the valvearms, will close off the supply of liquid until it has so far wasted as, by the dropping of the float, to again open the valves G and 0.

As the air or gas, in order to be passed through the stuffed chamber E, must be forced through under more or less pressure, it is desirable to employ the, valve 0, so as to keep this pressure from the gasoline, and also prevent air or gas from escaping while the main tank is being filled. An apparatus of this character serves the double purpose of charging the air or gas with hydrocarbon vapor, and at the same time filtering it of all impurities in its passage through the chamber E. This apparatus may be located either above or below the ground, as may be desired.

When liquid hydrocarbon is permitted to stand at rest its lighter and more volatile ingredients rise to the surface. In order, therefore, to secure a light of uniform and regular brilliancy, I so construct my apparatus that the liquid employed is constantly drawn from the bottom of the supply-tank from which the lighter matter has ascended and separated it self.

I am aware that it is. not new to provide a gascarbureter having a hydrocarbon-supply chamber, a carbureting-chamber with a perforated diaphragm, and a valve-chamber and valve located therein for automatically governing the flow of hydrocarbon from the supply-ch amber to the carbureting-chamber, and hence I would have it understood thatI make no broad claim to such a construction or combination of parts in a gas-carbureter; but

What I claim is- 1. In a carbureter, the combination, with tank A, for liquid hydrocarbon, feed-chamber B, carbureting-charnber E, filled with capillary substance, and chambers B and E, separated by aperforated partition, of the Valves 0 O valvestem D, and float D, substantially as set forth.

2. In a carbureter, the combination of carbureting-chamber E, tank A, located over chamber E, feed-chamber B, the latter cover ing the ends of chambers A and E, valves 0 O, stem D, and float D, substantially as set forth.

Witness my hand at Pontiac, Michigan, this 8th day of September, 187 9.

CHARLES A. HOWARD.
